Top hinge loose, making the bottom fall inwards towards the door frame? If nothing obvious, I'd plane it down and be done. Someone wiser/more knowledgeable than me might have much better suggestions.
Edit: I assumed it's the hinge side sticking, not the latch side. But I don't know how I arrived at that conclusion.
Our porch rises and falls with the seasons, unfortunately our door is on the same plane and periodically sticks so I have 3 positions where I can move the (enlarged) strike plate.
